guys, i just bought my wii (USA version) from HK. i was told that it contained wiikey, but may i know how should i check with it so that i will not be conned? coz rite now, i only have a game that comes with it Wii sport, as for the backup copy, still haven't got it. oso, after i bought the wii, i walk around, and heard that some1 is asking if the wii has been updated to 2.2J version, then last nite, i play with my wii, found that its only 2.0, so may i know whats the difference between these firmware? can we update the firmware ourself? will it cause the wiikey to stop functioning? thanks.
